In addition to the numerous interior and exterior luxury enhancements that all GS models receive, base prices remain unchanged for the GS 350 and GS 450h hybrid at $44,150 and $54,900 respectively. The GS 460 replaces last year's GS 430, and features a new 4.6-liter V8 engine that provides an additional 52 horsepower, for a total of 342 horsepower. The new GS 460 receives a modest increase of 0.47 percent over the model it replaces, or $245, to $52,620.

2008 GS Model Enhancements

All 2008 Lexus GS models will receive significant interior and exterior revisions, including an enhanced front fascia showcased by a new front bumper and an aggressive new chrome grille surround. GS models also gain side-view mirror turn signals for additional visibility. GS 350 models will come with new standard 17-inch alloy wheels or new 18-inch alloy wheels as an option.

Interior changes to all GS models include a new brushed-aluminum shift-plate that is subtly contrasted with additional wood trim on the door switch plates. The instrument panel and combination meter also have a revised appearance. For added convenience, the fuel-filler door release and trunk-release buttons have been relocated from the drop-down switch box to the dash area. GS models will also feature a newly designed leather-trimmed steering wheel as standard, with a wood-and-leather-trim steering wheel offered as an option. Every GS model will include an MP3/iPod/WMA port allowing use of portable music devices.

2008 GS 450h Upgrades

The Lexus GS 450h remains the only hybrid luxury sport sedan. In addition to the aforementioned upgrades, the GS 450h is fitted with heated and ventilated semi-aniline leather trim front seats as standard equipment. Remaining consistent with the LS 600h L and RX 400h luxury hybrids, the GS 450h will sport a blue hybrid designation on the side rocker moldings, aluminum-and-blue enameled rear model designation, a Lexus Hybrid Drive engine cover, blue trimmed front and rear "L" logos, a blue tint to the headlamps and a power meter that replaces the tachometer. A VDIM cutoff switch was added to allow an experienced driver to disengage the stability system.

More Powerful GS 460

The GS 460 is the latest addition to the GS family as it replaces the previous GS 430 model. The GS 460's 4.6-liter V8 engine, first introduced in Lexus' flagship LS 460, produces a commendable 342-horsepower and 339 lb-ft of torque, which is 20 lb-ft more than the model it replaces. Increased performance is a result of new engine technology; in particular, the world's first electric motor-driven Variable Valve Timing with intelligence and Electronically controlled intake cam (VVT-iE). Additionally, a dual fuel-injection system that utilizes both port and direct injection optimizes efficiency and allows high compression (11.8:1) for power and efficiency. Paired with the segment's first 8-speed automatic transmission, the GS 460 can accelerate from 0 to 60 in an intense 5.4 seconds while achieving Ultra Low Emission Vehicle II (ULEV-II) certification.

In addition to the changes made on all 2008 GS models, the GS 460 adds semi-aniline leather trim and ventilated front seats as standard luxury features.
